Abstract: In a component casing, especially a relay, which has a ventilation opening, this ventilation opening (6) opens in the interior of the casing into an insulation shaft (11) which is separated from the metallic parts (2, 3, 4) in the interior of the casing by an insulating wall (12), originating from the casing wall (5a), and which is open to the interior of the casing at least on its end (11a) located opposite to the ventilation opening (6). In consequence, the necessary insulation paths between the live parts (2, 3, 4) in the interior of the casing and the adjacent metallic parts outside the casing are guaranteed, even after opening the ventilation opening (6).

Abstract: Transdominant repressors of viral gene phenotypic expression derived from the  rev  gene product of HIV-1 or the  rex  gene product of HTLV-1 and corresponding mutated genes are described', having the capability of repressing the Rev function in HIV-1 and/or the Rex function in HTLV-I and HTLV-II. Transient gene expression analysis of a series of missense and deletion mutants has been used. 
     Some of the mutants found repress both the Rev and the Rex function and are thus active in more than one viral species. 
     Transdominant viral mutants represent a promising new class of anti-viral agents. Cellular expression of these transdominant inhibitors may be used in such therapeutic approaches as intracellular immunization in order to protect cells against the deleterious effects of viral, e.g. HIV-1 infection.

Abstract: The invention proposes a mechanical or hydraulic press with a drawing device for drawing work or drawing station of a multiple stage press, in which the blank holding performed by a platen is effected by means of hydraulic clamping. In order to damp the impact which occurs when the top tool (7) strikes the platen (6) and, especially to damp the impact noise and to perform the subsequent drawing operation by means of positive control, the movement of the press ram (8) is transmitted to a pumping cylinder (12), the hydraulic fluid of which acts on a further pressure cylinder (17), which is connected to the die cushion (10) to give a preliminary acceleration. The clamping of the die cushion takes place via an accumulator (21) after the preliminary acceleration has been effected. <IMAGE>

Abstract: A rotary speed sensor system uses a permanent magnet (14) and a Hall cell (16) sensitive to the changing tangential component of magnetic field caused by the interrupted surface profile of a rotary element (10). In order to avoid anomalies caused by the variation of the base value of the tangential component of magnetic field, the output of a differential amplifier (OP1) fed by the Hall cell (16) is connected to a voltage averaging means (OP2, R5, C1) which stores the average voltage on a single capacitor (C1). The output of the differential amplifier (OP1) and the voltage across the capacitor (C1) are respectively coupled to the differential inputs of a Schmitt trigger (19) exhibiting hysteresis. The Schmitt trigger (19) thereby establishes operate and release points relative to the average voltage signal. The voltage averager (OP2, R5 C1) is a non-linear circuit in which the voltage across the capacitor (C1) is fed back to the negative input of an operational amplifier (OP2). A power-­up circuit (OP5, R10, D1, Q2) is also provided for rapidly charging the capacitor (C1) initially to approximately the average voltage.

Abstract: Pullulan and dextran promote the growth of bifid bacteria in human and animals. Such promotion is effective in maintaining and improving health and beauty, as well as in preventing and/or treating diseases such as geriatric diseases, hyperammonemia and hepatic encephalopathy. The presence of certain oligosaccharide(s) such as lactulose, raffinose, lactosucrose, isomaltooligosaccharide, fructooligosaccharide, galactooligosaccharide and xylooligosaccharide greatly enhances such promotion. Thus, pullulan and dextran are advantageously usable for or in health foods, pharmaceuticals, animal feeds and pet foods.

Abstract: The read head (24) is asymmetric, being formed by an inclined (oblique) conical section. The image of the latent information that it provides is deformed or "skewed" with respect to that which would be provided by the same read head if it were perfectly symmetric (right conical section). This results in the various categories of users of the installation being able to be equipped with different read heads each providing its own image of the information made visible, which avoids any risk of indiscretion, each category of users having access to a part of the stored data corresponding to the specific image which its own read head provides for it.

Abstract: A self-aligned masking process for use with ultra-high energy implants (implant energies equal to or greater than 1 MeV) is provided. The process can be applied to an arbitrary range of implant energies. Consequently, high doses of dopant may be implanted to give high concentrations that are deeply buried. This can be coupled with the fact that amorphization of the substrate lattice is relatively localized to the region where the ultra-high energy implant has peaked to yield a procedure to form buried, localized isolation structures.

Abstract: A detection signal from a multi-wavelength detector provided in a liquid chromatograph is stored in a data storage part, and a chromatogram is formed from the stored data with respect to a specific wavelength, to detect a peak from the chromatogram. The spectrum at a top of the peak to be identified or a known spectrum of a component to be identified is used as a reference spectrum, to calculate the degree of coincidence between the spectrum at each position of the chromatogram peak and the reference spectrum as fraction purity at each position of the chromatogram peak. The calculated fraction purity values are classified in colors, for example, and displayed on a display part. Thus, it is possible to readily decide whether the measured peak consists of a single component or at least two components, and which time range consists of a single component.

The gate, source and drain electrodes of the second TFT are coupled respectively to the same scanning line to which the gate electrode of the first TFT is coupled, the electrode of the same pixel and the electrode of a succeeding pixel provided on the opposite side of the scanning line to the same pixel. The arrangement also has a scanning driver circuit capable of activating two scanning lines at the same time for sequential one-by-one scanning operation, whereby no fault in a reproduced image will be perceived in spite of the presence of a defective TFT.
